Tooth Grade - SDE Series
Silicon dioxide for SDE series’ toothpaste is amorphous powder, which is tasteless and insoluble in water or
acid, showing as chemical inertness, with good compatibility with fluoride and other materials in toothpaste.
The structure and particle size of silicon dioxide can be controlled by production condition. By aiming at
different types of toothpaste,China Prototype Pcb Fabrication - Electronics FFC/FPC Connector Flexible PCB Manufacturer - FASTPCBA Technology Co., Ltdmade: friction type, mixed type and thickening type.
